While driving home from his grandson’s baptism, the hero walks into a space-time trap and is spirited to the world of Slormor. It is a tired world, populated with beings who eke out an existence. To them neither life nor death seems desirable.

As the hero tries to find a way back to his own world, a little girl, Parvrin, becomes his companion and guide. She shows him that under the green sun of Slormor, things are not always as they seem. A series of strange adventures leads him back to his grandson’s baptism, where a kind of final explanation — if explanation it is — leaves him astounded.
